Hyperthread Machine equivalent to a Intel Xeon E5-2650 (8 Cores, 2.00 GHz)

[Omar Yesith Alvarado Gonzalez]

Hi!

I'm trying to dimensionate the equivalent processing capacity of a Intel Xeon E5-2650 (8 Cores, 2.00 GHz) for a Google Compute Engine Instance.

What type of instance may I use to obtain the processing capacity equivalent to these processor??

I don't understand what exactly mean when in the documentation say: "For the n1 series of machine types, a virtual CPU is implemented as a single hardware hyper-thread on a 2.6GHz Intel Xeon E5 (Sandy Bridge), 2.5GHz Intel Xeon E5 v2 (Ivy Bridge), or 2.3 GHz Intel Xeon E5 v3 (Haswell)."

With the Intel Xeon E5-2650, I have 8 cores, so with the HyperThreading this is equivalent to have 16 threads.  Now, for a single vCPU implemented as a "single hardware hyper-thread" as described in the documentation, ¿how many threads I get?

¿Perhaps a n1-standar-8 instance may be equivalent?

Thanks!

Hi Omar,

Basically, 1 virtual CPU == 1 vCPU == 1 hyperthread == 1/2 physical core. The underlying CPU platform you get depends on the Zone you run the VM in (table here).

So, in terms of core/vCPU matching with your Intel Xeon E5-2650, you would select GCE's n1-[standard|highcpu|highmem]-16 machine type, depending on how much RAM you want (or create a custom machine type if none of the predefined types quite matches your workload).

Let us know if you have additional questions.

Scott!

Thank you very much, now I have clear how to dimensionate this.

Greatting!
